So everyone knows that Zod is coming to Smallville. How, why and
from where? Did the Zod-zoner come out and posess someone else? Did
Brainiac wizz in a cup and it magically formed Zod? Or is something
else entirely happening here?

We keep hearing purposefully p.o.s explanations so that no big
secrets will be given away. "All I'll say is that i'm not actually
going to say anything that is even slightly relevant to what we're
talking about but it's better than getting c<m in your eye".
That's what they're telling us.

Here's what I think. Thanks to my research I've read that this Zod,
Major - not General, comes from somewhere in Krypton's past. Maybe
he's been on Kandor and comes out when Tess opens up the portal

Lois comes back from the future with the Legion flight ring and
throughout the season until the mid-season cliffhange has visions
of the possible future which will happen if Clark doesn't stop it.
Now all of this information, obtained from Kryptonsite.com, leads
me to believe that at some point this season Lois will find out
that Clark and the Blur are the same person. And a teaser trailer
for the new season show Lois making love to someone who looks an
awful lot like Clark, which will be amazing considering Clark
always has that "I can't do it because I don't trust myself with my
powers" mindset going on. It also feels to me as though Lois will
be the one to bring Clark back to humanity's fold and convince him
to re-embrace his humanity. …
